Beamer: Line spacing in title

Question

I have a long title for my beamer presentation and ue the \titlepage{} command. The title is automatically split over 4 lines. As I am using a tall font (arev), these lines are squashed together. I can use something like \newline \vskipt6pt where the line breaks occur to get roughly what I want (using \\ seems to insert a spurious comma). I am using the contributed Torino theme. This there a way to `automatically' increase this spacing for the title only?

Answer 1

You can use \fontsize to control the font size (first argument) and the value of \baselineskip (second argument); usually, the value for the second argument is aprox. 20% more than the first argument, but you can use the value that best suits your needs:

\documentclass{beamer}
\usepackage[T1]{fontenc}
\usetheme{Torino}
\usepackage{arev}

\author{T.H.E. Author}
\title{\fontsize{28}{35}\selectfont A really really  really  really  really  really  really  really  really  really  really  long long title}

\begin{document}
\begin{frame}
  \titlepage
\end{frame}

\end{document}

Answer 2

Alternatively, you can edit the innertheme file and add something like

\setlength\lineskip{6pt}

right before the \inserttitle command.

If you want to use Torino with the alternativetitlepage option, you have to go this way, because there is a \offinterlineskip command that overrides what you set.
